A Mobile Application to Improve Procurement and Distribution of Healthful Foods & Beverages in Baltimore City

Completed · Not applicable

Conditions studied: Obesity

In brief

Low-income urban communities have many small food stores, but poor access to healthier foods and beverages. The investigators will develop, implement and evaluate the feasibility of a Baltimore Urban food Distribution (BUD) web-based application (app) to improve access to affordable, healthier products from local producers/wholesalers in 38 urban corner stores in low-income Baltimore neighborhoods, using a randomized controlled trial design and assess its impact on store stocking and sales. The R34 will provide a developed and tested version of the BUD app, which will resolve challenges related to affordability and delivery of healthful foods and beverages to small food stores, permit development of new instruments, assess potential impacts at the consumer level, permitting power and sample size estimates for the full-scale clinical trial, and demonstrate the investigators' ability to recruit and retain large numbers of wholesalers, producers, and corner stores in low-income urban settings.
